Selecting U-Bolts Using Pipe, Conduit, or Tubing Trade Size
More
U-Bolts
Stronger than routing clamps and hangers, U-bolts support heavy pipe, tube, and conduit from ceilings, walls, and poles. Zinc-plated steel U-bolts have good corrosion resistance in most environments. Galvanized steel U-bolts have better corrosion resistance than black-oxide and zinc-plated steel U-bolts. 304 stainless steel U-bolts have excellent corrosion resistance and good chemical resistance. 316 stainless steel U-bolts have excellent corrosion and chemical resistance.
U-bolts with four nuts allow you to secure the U-bolt from the top and the bottom.
